Post your best office holiday party story!

I just got back from my departmental holiday party and it was a blast (nice buffet, open bar, DJ with funny-stupid games. I merrily watched a couple of drunk coworkers make fools of themselves on the dancefloor...Oh and there was indeed pictures and videos taken..If I get my hands on some pics I might have to post one (yes I was a dancing fool myself:) )
But I was sharing some funny stories about past office parties, including one company where the CEO got drunk and started dancing wildly (and very dorkily) near me and a friend on the dance floor and almost knocked us over as he veered accross the floor.
I know there are some wonderfully juicy stories out there..Please share your favorites!!:beer:
